Organized search and rescue attempts to find the hiker who disappeared on Mount Tamalpais have been suspended and the park service is now in investigative mode working with the hiker's parents, an official said Monday.

More than 100 volunteers, helicopters, dogs and more than five public agencies searched over the weekend for Magdalena Glinkoski, who was last seen wearing a pink top, shorts and running shoes in a video March 30 as she walked across the parking lot to hike the mountain.

"No one is looking for her (Glinkoski) as part of the search and rescue team, though there might be volunteers doing so," said Rose Blackburn, a California State Park supervising ranger. "We have the parents here trying to get information from them."
